Gunn will play one of the lead roles in Detective Ellie Miller, a life-long resident of Gracepoint, a tranquil beach town that’s thrown into turmoil when a young boy is killed. Olivia Colman played the same role on “Broadchurch.”

Weaver, meanwhile, is set to play Susan Wright (portrayed by Pauline Quirke on “Broadchurch”), a standoffish resident of the town who gets caught up in the investigation.

“Gracepoint” will also star David Tennant, who will essentially reprise his role from “Broadchurch” as the troubled lead investigator on the case. “Broadchurch” creator Chris Chibnall is executive producing the remake, while “In Treatment” veterans Anya Epstein and Dan Futterman will serve as showrunners. The miniseries is scheduled to air during the 2014-15 season.
